Blancpain revives its tiny 1956 Ladybird as the spherical, lugless Lady B

Blancpain has unveiled the Lady B, a spherical mechanical watch that revives the 1956 Ladybird Bullet for its 70th anniversary. The case measures just 19mm in diameter and 13.2mm thick, a total volume of 2.9 cubic centimeters, and it dispenses with lugs entirely.

Instead of conventional lugs, a 10mm double-tour calfskin strap threads directly through a channel machined into the case, a construction that took more than 30 technical drawings to resolve. The strap can be swapped without tools, and the case comes in polished stainless steel or 18-karat red gold.

Pricing runs from $12,600 in steel to $19,200 in red gold, according to the US listing, though Blancpain's own materials cite CHF 9,500 and CHF 14,500 for the two versions. Both come on an opaline dial with applied gold or steel indices and pencil-style hands, and no exhibition caseback.

Who was the original Ladybird for

The original Ladybird was created under Betty Fiechter, who joined Blancpain as a 16-year-old apprentice in 1912 and became, in 1933, the first woman to own and lead a Swiss watch manufacture. She ran a company of more than 200 employees at a time when Swiss women could not yet vote.

Fiechter secured loans with commercial director Andre Leal to buy Blancpain after founder Frederic-Emile Blancpain's sudden death in 1932, and the firm had to be renamed because Swiss law reserved the Blancpain name for someone of that surname. Working with her nephew Jean-Jacques Fiechter, she then shaped two of the brand's defining families.

The Fifty Fathoms arrived in 1953 and became a foundation of dive-watch history, and the Ladybird followed three years later as an equally consequential feat aimed squarely at women. Blancpain, which describes itself as the oldest watch brand in the world, built both around movements it engineered and finished in house.

That Blancpain heritage runs through our own coverage of the brand, where we've traced how the manufacture built its name on mechanical watchmaking rather than the quartz movements that displaced much of the industry from the 1970s onward. The Lady B is presented as part of the permanent collection rather than a limited run.

At the heart of the original was the R55, a hand-wound caliber measuring 11.85mm across and 3.7mm thick, which remains the smallest round mechanical movement ever produced in series. It carried a fifth wheel to limit force on the escapement and a shock protector on the balance wheel, both durability features ahead of their time.

That miniaturization gave Blancpain's designers unusual freedom, and Ladybird movements ended up hidden inside bracelets, cuffs, rings, pendants and cufflinks rather than only conventional watch cases. The new Lady B does not attempt a literal reproduction of that watch, instead reinterpreting its bulbous, midcentury silhouette in a larger, automatic form.

Inside the Lady B is the Manufacture caliber 615, introduced in 1995 and refined over three decades, measuring 15.7mm in diameter and 3.9mm thick, making it one of the smallest automatic movements currently in production. It runs at 3 Hz, holds 180 components and 29 jewels, and delivers a 38-hour power reserve.

A silicon balance spring gives the movement resistance to magnetism, and Cotes de Geneve finishing decorates the caliber to the same standard expected of a full-size Blancpain movement, despite the watch having no exhibition caseback to show it off. The watch is rated to 30 meters of water resistance and shows only hours and minutes.

The double-tour strap is offered in white, light beige, dark beige, burgundy, fuchsia purple and blue, letting buyers change the watch's character without tools. Because the case has no lugs, the interior of the strap channel is micro-blasted so the 1.6mm-thick calfskin slides through more easily, and the edges are hand-finished to avoid sharp contact points.

How the Lady B compares with other revivals

The Lady B lands amid a wider run of heritage revivals we've been tracking in watches and jewelry, including Tudor's relaunch of the North Flag as the Northflag with a GMT function in place of its old power reserve display, and A. Lange & Sohne's platinum Triple Split, limited to 100 pieces at 210,000 euros.

Grand Seiko has similarly revived its first manual-winding 9S dial in a run of 600 pieces.

Unlike those men's-oriented reissues, the Lady B is explicitly built around a design brief for women rather than a scaled-down men's case, a distinction Blancpain and its retailers have highlighted. It carries no gemstones and keeps its opaline dial deliberately plain, leaning on shape and finishing rather than stone-setting for its visual impact.

Blancpain has revisited the Ladybird name before, including a Marilyn Monroe tribute unveiled earlier in the same year, but has not produced a case shape quite like the Lady B's spherical, lugless form in decades. The Lady B is now available to order directly through Blancpain's boutiques and retail partners in both metal options.
